If a function has multiple arguments, it is unspecified what order they are evaluated in. The following code could print x = 1, y = 2 or x = 2, y = 1 but it is unspecified which. int f(int x, int y) { printf("x = %d, y = %d\n", x, y); } int get_val() { static int x = 0; r...

To use additional packages within the Rcpp ecosystem, the correct header file may not be Rcpp.h but Rcpp<PACKAGE>.h (as e.g. for RcppArmadillo). It typically needs to be imported and then the dependency is stated within // [[Rcpp::depends(Rcpp<PACKAGE>)]] Examples: // Use the RcppAr...

Most printable characters can be included in string or regular expression literals just as they are, e.g. var str = "ポケモン"; // a valid string var regExp = /[Α-Ωα-ω]/; // matches any Greek letter without diacritics In order to add arbitrary characters to a string or regular expression,...

This code shows a simple example of animation in Unity. For this example, you should have 2 animation clips; Run and Idle. Those animations should be Stand-In-Place motions. Once the animation clips are selected, create an Animator Controller. Add this Controller to the player or game object you w...

This is a snippet of master report. Two parameters and the connection (for example, jdbc) are passing to the subreport. One value is returned from the subreport back to the master report, this value (variable) can be used in master report <subreport> <reportElement x="0" y=&...

Classification in Machine Learning is the problem that identifies to which set of categories does a new observation belong. Classification falls under the category of Supervised Machine Learning. Any algorithm that implements classification is known as classifier The classifiers supported in P...

In classification using PHP-ML we assigned labels to new observation. Regression is almost the same with difference being that the output value is not a class label but a continuous value. It is widely used for predictions and forecasting. PHP-ML supports the following regression algorithms Suppo...

Interprocess communication allows programmers to communicate between different processes. For example let us consider we need to write an PHP application that can run bash commands and print the output. We will be using proc_open , which will execute the command and return a resource that we can com...

An enumerations value in no way needs to be unique: #include <stdlib.h> /* for EXIT_SUCCESS */ #include <stdio.h> /* for printf() */ enum Dupes { Base, /* Takes 0 */ One, /* Takes Base + 1 */ Two, /* Takes One + 1 */ Negative = -1, AnotherZero /* Takes Negativ...

Classes have instance variable (dependencies), on which they call methods. Example taken from http://www.jamesshore.com/Blog/Dependency-Injection-Demystified.html for reference public class Example { private DatabaseThingie myDatabase; public Example() { myDatabase = new DatabaseTh...

Basic Syntax Julia's array comprehensions use the following syntax: [expression for element = iterable] Note that as with for loops, all of =, in, and ∈ are accepted for the comprehension. This is roughly equivalent to creating an empty array and using a for loop to push! items to it. result ...

Enumeration types can also be declared without giving them a name: enum { buffersize = 256, }; static unsigned char buffer [buffersize] = { 0 }; This enables us to define compile time constants of type int that can as in this example be used as array length.

There is a mantra that some Java experts are wont to recite: "Exceptions should only be used for exceptional cases." (For example: http://programmers.stackexchange.com/questions/184654 ) The essence of this is that is it is a bad idea (in Java) to use exceptions and exception handli...
